Default Sagging rear springs cheap fix? Helper springs.

I've driven multiple sqbirds for decades, including 14 years as daily drivers in the late 60s through the early 80s. My quick trick was to install cheap leaf helper springs (easy to find) on the rear, which raised the car a bit, plus added some much needed stiffness to the too soft (imo) factory springs. That tightened up the handling as well as adding load capacity. The first time I tried helper leaf springs was after I added a continental kit to my daily driver in '69, which really made the rear end sag (I carried two spares which didn't help) and made the handling mushy. Adding the helper springs really helped.

Or try booster spring ("load-leveller") rear shocks, either built-in (hard to find) or booster springs over your existing shocks (easy to find). I recently put Monroe gas-charged load-levellers on a '58, which are notorius for too soft rear coil springs that sag & sway.

I've never tried new springs. I've seen cars with new springs or re-arched springs that either sat too high or still sagged, so I always stopped short of spending the big $ when the outcome was iffy.

I also put front load levellers on the front of a couple of sqbirds that sagged in front. That really helped on a 430 (every 430 I've ever seen sags in the front due to the extra weight of the big engine & tranny).

I would also be curious which shocks you used. Here is a ebay link: http://www.ebay.com/itm/1959-1963-Ford-Thunderbird-Monroe-Air-Shocks-Rear-ext-17-625-Compressed-11-/380437935466?pt=Motors_Car_Truck_Parts_Accessories &fits=Year%3A1960|Model%3AThunderbird|Make%3AFord& hash=item5893de356a&vxp=mtr
I used to also see a auction for Gabriels, but I can't find it now.

I'd be interested in the air shocks you used too. I know that some don't like them, but had on Squarebird owner tell me it was like floating.

My next door neighbor (God rest his soul) was a retired trucker. He had a Granada that he added one leaf to. Mind you, he never carried anything heavier than a fishing pole and a tackle box, but that was the ride he loved.

Rather than adding shock helper springs or air bag shocks, you may consider adding a leaf to your car.

Leaf springs for our cars are very common and available. I found them easier than I thought to change. Come to think of it, I had one front bolt that really didn't want to come out so I cut it in half.

Anyway, start with new springs. If you want a stiffer ride, let the shock absorbers do that. The springs offer suspension and the shocks offer ride. I'm using large-diameter SUV shocks on our Galaxie. They're GREAT! The suspension finally does what it was intended to do. The ride is not mushy like most classic shocks give, it's just smooth like a modern rear wheel drive vehicle. - Dave

Once upon a time in a galaxy far far away...

...one could buy differing shock rates, i.e. STD, PREMIUM, HD and XHD. Those options are gone now and fitting heavier shocks to an application as Dave has done is about the only practical solution.

The key is having quality springs that are calibrated properly to the application (taking into consideration there is no frame sagging/collision damage and all suspension parts are within specifications).

-EATON DETROIT SPRING-

Just a word of caution. Air shocks will put greater stresses on the shock mounting points (especially with worn springs) so watch for fatigue. They (mounting locations) may have to be reinforced.

Here is some information that Gary sent me to post on Auxiliary Air Spring Kits. To zoom in use Ctrl +

Do it up right and get some air springs.

In all actuality, if the rear suspension cannot be returned to specs (or greater) or one cannot afford the necessary parts, air bags are about the only way out. They can be regulated to whatever ride quality one desires.

Fooling around with worn out springs is not the way to go about it (IMO).

Default Reversed the shackles car looks better?, rides better...

My ride height is now = (352 non-AC)
Fender lip to center of hub cap
Rear 7"- 8"
Front 15 1/2" - 16" this height gives it a tail dragger look, with consensus being 14" - 14 1/2" as being normal I guess I can live with this for now.
I dont know why it sits so high unless maybe a previous owner installed bigger springs (it looks as if someone has done work on the front end in the last 10 or 20 years, the car had sat in storage for 6+ years when I got it).
I installed Monroe #5801 Sensa-Trac Passenger Car shocks on the front. Dont think that would give the front end any extra lift
Shock spec's
Compressed Length 9.250"
Extended Length 14.375"
Travel 5.125"


With the shackles hanging down there was a hard bounce going over speed bumps. That is now gone and it goes over speed bumps smoothly.
